How can you tell the difference between wood suffering from brown
rot and wood suffering from white rot? - ANSWER-Wood infested with
brown rot typically:
• appears dark brown,
• shows excessive shrinkage,
• develops cross-grain cracking, and
,• can be crushed easily to form a brownish powder.
Wood infested with white rot on the other hand, often:
• appears whiter than normal,
• shows normal shrinkage,
• does not crack across the grain,
• is spongy to the touch.
What is the difference between the stains caused by stain (sapstain)
fungi vs. mold fungi? - ANSWER-Sapstain fungi live on the starch in
wood cells. These fungi may discolor the sapwood entirely or in
,patches. This stain is deep within the wood and cannot be removed by
brushing or planning.
On the other hand, discoloration caused by mold fungi is superficial.
This means that you can usually remove the discoloration by brushing
or planning. However, on hardwoods with open pores (very large and
visible vessels) such as the oaks, the surface molds may cause stains
that are too deep to remove easily.
How can you distinguish between winged termites and winged ants? -
ANSWER-Look at their antennae, waists, and wings. Winged termites
have straight antennae, thick waists, and wings that are equal in size
and shape. Winged ants have bent antennae, narrow waists, and
forewings that are larger than the hind wings.
Name the four basic castes of termites. Describe the basic function(s)
of each caste. - ANSWER-Workers - gather food, maintain the galleries,
tend the young, and groom the other termites.
Soldiers - guard the colony against predators.
Primary reproductives - "swarmer’s" that fly out of their colonies to
start new colonies of their own. They are the future kings and queens
of new colonies.
, Secondary reproductives - supplement egg production in the presence
of the king and queen and can take over the egg laying if the queen
dies or begins to fail.
Do subterranean termites live entirely within wood? Why or why not?
- ANSWER-No, because they require a constant source of moisture to
survive. However, they can live in wood with less than 20% moisture
by getting their moisture from the ground. They transport this
moisture through flattened, earthen shelter tubes that serve as
passageways from the soil to the infested wood.
How do subterranean termites most often infest wood in buildings? -
ANSWER-They gain entry through untreated wood that touches or is
close to the ground, particularly at porches, steps, and terraces. They
can also infest buildings through cracks or voids in foundations or
concrete floors that make it easy for termites to reach wood that is
not close to the soil.
Describe the frass pellets of drywood termites. - ANSWER-They are
small and cylindrical with six depressions on the sides. These pellets
are unique to drywood termites and are used for identification.
Where do drywood termites most often occur? - ANSWER-In southern
Florida, southern California, and along the southern gulf coast of the
United States.
Do drywood termites live entirely within wood? Why or why not? -
ANSWER-Yes, because they require little moisture (wood MCs as low
as 5%). Unlike subterranean termites, drywood termites have no
connection with the soil.
